| 摘 要： | 动态电压恢复器(dynamic voltage restorer,DVR)是用于电能质量控制的主要设备之一。文章设计了一种DVR拓扑结构,不同于传统三相独立补偿单元的DVR,它针对三相三线制电网,采用2个独立补偿单元,经由滤波电容直接串入主电网。根据技术要求设计实现的原理样机采用无差拍控制,通过线电压检测进行电压跌落补偿。实验证明,原理样机能及时检测系统电压扰动,并予以准确的补偿。

| Abstract: | Dynamic voltage restorer(DVR) is one of important devices for power quality control.In this paper a novel topological structure of DVR is proposed.Different from traditional DVR adopting three-phase independent compensating units, aiming at three-phase three-wire power grid, the proposed DVR adopts two independent compensating units and is directly connected in series with main power network via filter capacitors.According to technical requirements the deadbeat control is applied to implemented principle pr... |
